Configuring Rip Frr - HPE FlexNetwork HSR6800 Configuration Manual

To configure the RIP packet sending rate:
Step
Enter system view.
1.
Enter RIP view.
2.
Specify the interval for
3.
sending RIP packets and the
maximum number of RIP
packets that can be sent at
each interval.

Configuring RIP FRR

When a link in a RIP network fails, the traffic is interrupted until RIP completes routing convergence
based on the new network topology.
You can enable RIP fast reroute (FRR) to reduce traffic recovery time.
Figure 6 Network diagram for RIP FRR
In Figure 6, after you enable FRR on Router B, RIP designates a backup next hop using a routing
policy when a network failure is detected. Packets are then directed to the backup next hop to reduce
traffic recovery time. At the same time, RIP calculates the shortest path based on the new network
topology, and forwards packets over that path after network convergence.
Configuration prerequisites
Specify a next hop by using the apply fast-reroute backup-interface command in a routing policy
and reference the routing policy with RIP FRR. For more information about routing policy
configuration, see "Configuring routing policies."
Configuration guidelines
•
RIP FRR is only effective for non-recursive RIP routes (that are learned from directly connected
neighbors).
•
Do not use RIP FRR and BFD (for RIP) at the same time. Otherwise, RIP FRR might fail to take
effect.
Configuration procedure
To configure RIP FRR:
Step
Enter system view.
1.
Configure the source

By default, an interface sends up
to three RIP packets every 20
milliseconds.
